T-Ball Swage & Fittings

T-Ball Backing Plates are used on Masts to provide a sleek, lightweight, non-protruding attachment for Rigging. Common fittings for them include Swage and Mechanical terminals for Wire, as well as those for attachment of Rope and Rod fittings. As measurements vary widely, it is recommended that T-Balls be replaced only with the same type as original.
